本研究的目的是建立以下方法，以回应社会对绿化的需求。即使在突发性故障等不确定情况下也能保持电力不中断。电力系统规划灵活性的评价方法一直是一个多目标优化问题；2 .一种新的高效随机场景创建算法。考虑故障条件的配电规划方法。本研究项目的研究成果如下：提出了一种新的电力系统规划灵活性评价方法。在该方法中，利用解的逆投影的概念来评价柔性。通过编写算法的计算机程序，对所开发的算法进行了验证。此外，本文还建立了一种新的柔性发电机组检修调度方法。利用混沌的概念和遗传算法，提出了一种新的高效随机场景生成算法，并进行了试验。研究了混沌概念在创建随机场景中的充分性。然而，到目前为止，还没有找到明确的答案，即混乱是否可以用于创建场景。提出了一种考虑故障案例和多年规划的配电系统规划新方法，并通过编制计算机程序进行了验证。上述研究成果已在国内外多个会议上发表。部分优秀成果已提交给日本IEEE学报和IEEE学报。一些结果在交易中公布，如下一页的参考文献所示。

The purpose of this research is to establish the following methods so as to respond the social needs of rece.ving electrical power without interruptions even under such uncertainties as sudden faults.1. Evaluation method of flexibility of the electrical power systems planning which always be a multi-objective optimization problem,2. A new efficient random scenario creation algorithm,3. Distribution planning method in which fault conditions are taken into consideration.The followings as the reserch result of this research project.1. A new evaluation method of the flexibility of the power systems planning is developed. In the method, the concept of inverse projections of the solutions is used to evaluate the flexibility. The developed algorithm is tested by developing the computer program of the algorithm. More-over, a new flexible generator maintenance scheduling method is established as a by-product of this research.2. A new dfficient random scenario creation algorithm in which the concept of the chaos and the genetic algorithm are used is developed and tested. The adequacy to use the concept of the chaos in creating a random scenario is investigated. However, the clear answer is not found whether the chaos can be used in creating the scenario, so far.3. A new distribution systems planning method in which the fault cases and multi-year planning are taken into account is developed and tested by developing the comoputer program.The above research results are presented in many international and domestic conferences. Some of the fine results are submitted to the transactions of IEE of Japan and IEEE.Some of the results are published in the transactions as shown in the references in the next page.
